FOLDABLE WINDOW-SCREEN.

Specification of Letters Patent.

Application filed February 20. 1911. Serial No. 609,605.

To all whom 'it may concern:

Be it known that I, ULRICH SPRiNcHoRN, formerly a subject of the King ofSweden, having formally declared my intention to become a citizen of theUnited States, residing at Jamestown, in the county of Chautauqua andState of New York, have invented a new and useful FoldableTindow-Screen, of which the following is a specification.

The invention relates to improvements in window screens.

The object of the present invention is to improve the construction ofwindow screens, and to provide a simple, practical and serviceablewindow screen, adapted to be readily applied to a window, and capable,when the window is closed, of folding automatically in a compactcondition at the top and bottom of the window frame or casing, wherebyit will beout of the way and will also be protected from wind andweather.

- Tit-h these and other objects in view, the invention consists in t-lieconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size without departing from the spirit or sacri-- ficing anyof the advantages of the inven tion.

sectional view of a window frame, provided with automatically foldablescreens, constructed 1n accordance with this invention.

Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1. Figs. 3.and 4 are detailv perspective views, illustrating the construc-i gularform of the sections stiens them and renders the wire gauze lesspliable, and also produces a positive folding of the section in theproper direction, as hereinafter fully eX- plained. The angular sectionsmay be reinforced at their end edges by substantially U-shaped metallicbinding strips 6, constructed of sheet metal and bent to form twoengaging sides or flanges and a connecting `bend, as clearly illustratedin Fig. 3 of the drawing. These metallic binding strips may, however, beomitted when desired.

The sections of thel automatically foldable window screen are hingedtogether at their adjacent .edges by a spirally coiled wire 7, or othersuitable means, and they are arranged to fold or nesttogether in themanner illustrated in Fig. 3 of the drawing. Any other suitable means,however, may be employed for hinging the adjacent edges of the sectionstogether. The spiral wire 7 is passed through the'meshes of the sectionsand forms an eflicient means for hinging i them to one another. Thesections 2 are of a In the drawing r--Figure 1 is a vert-ical width toextend across t-lie space between the walls of the guides or ways 8 and9 for the upper and lower sashes 10 and l1 of the window frame or casing12, and the guides for the sashes also serve to guide the sections ofthe window screen. The window screen, which is connected with the upperedge of the upper sash l0, is hinged at its lower edge to the same bymeans of a metallic strip 13, provided with spaced eyes 14, preferablylocated at the ends and at the center of the strip and receiving apintle rod 15 to which the lower edge of the foldable window screen isconnected by a spirally coiled wire 16. The upper edge of the windowscreen of the upper sash is hinged to the window frame or casing in arecess 17 thereof by a metallic strip 18 and a pintle rod 19. Themetallic strip 18 is constructed similar to the metallic strip 13, beingprovided with spaced eyes arranged at intervals to receive the pintlerod 19, which is connected with the windo-w screen by a spiral wire orother suitable means. When the upper sash is raised, the angulaisections of the window screen will fold compactly upon the upper edge ofthe said sash, and when the latter is closed or raised to the limit ofits upward movement, the window screen is completely folded andconcealed in the recess 17, and is protected by the window casing fromwind and the weather.

The window screen of the lower sash is reversely arranged, its. upperedge being connected to a metallic strip 20, secured to the outer faceof the lower sash and provided with spaced eyes 21, receiving a pintlerod 22 to which the upper edge of the window screen of the sash issecured by a spiral wire, or other suitable means in the manner beforedescribed. The metallic strips may be secured either to the side facesor the end faces of the sashes. The lower edge of the foldable windowscreen of the lower sash is hinged within a lower recess 23 of thewindow frame or casing by a metallic strip 24;, having spaced eyesreceiving a pintle rod 25, which is connected with the lower edg'e ofthe window screen by a spiral wire in the manner heretofore explained.Vlien the window screen of the lower sash is folded within the bottomrecess, it is also concealed from view and is protected from the windand weather. jWhen t-lie upper sash is raised, or the lower sash islowered, the slackening of the window screen causes the sections to foldback and foith in Zig-zag relation, and the angular shape of thesections with their alternate reverse arrangement causes the sections tofold and nest properly. The screen is readily extended or unfolded wheneither the upper sash is lowered or the lower sash is raised.

In the accompanying drawing, the saslies 10 and 1l are counter-balancedby means of opposite racks 26 and 27 and a centrally arranged pinion 28,meshing with the racks, as clearly indicated in F ig. l of the drawing,but any other suitable means for balanc ing the sashes may be employed,as the window screen is applicable to all kinds of saslies, whetherbalanced or unbalanced and may be used on a window with a single sliding sash as well as on windows having upper and lower sashes.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

l. A foldable window screenincluding a plurality of similar anglesections hinged together at their adjacent edges, said sections havingangularly related sides or wings and being alternately reverselyarranged to enable them to fold and nest compactly.

2. A foldable window screen including a plurality of sections hingedtogether, each section being constructed of a single piece of wire gauzebent to form two sides or wings, the material being folded inwardly onthe sides or wings to form reinforcing plies or thicknesses.

3. A foldable window screen including a plurality of transverse anglesections hinged together at their adjacent edges and consisting of twosides or wings, the material being folded inwardly on the sides or wingsto` form reinforcing plies or thicknesses, and approximately U-sliapedmetallic binding strips embracing the end edges of the sections andengaging the plies or thicknesses and retaining the same in position.

4;. The combination with a window frame having a giiicle\vay, and a sashmovable in the same, of a foldable window screen coinposed of aplurality of angle sections hinged together and alternately arranged inreverse relation so as to fold and nest compactly, said sectionsoperating in the guide-way of the window frame, means for hinging thescreen to the sash and to the window frame, said means including ametallic strip provided with spaced eyes, a pintle mounted in the eyes,and a spiral wire connecting the screen with the pintle rod andembracing the latter.

In testimony, that I claim the foregoing i" Copies of this patent may beobtained for ve cents each, by addressing the Commissioner of Patents,Washington, D. C.
